Overall, I like Face ID a little better than Touch ID. Face ID
works on the first try most of the time, but even without Require
Attention it fails to recognize me more often than Touch ID does.
And, perhaps due to an iOS change, even when it seems like it did
recognize me, I need to type my passcode multiple times per day.
When the phone is in my pocket, Face ID feels slower than even the
iPhone SE’s Touch ID. Even with first-generation Touch ID, I could
put my finger on the sensor and have the phone unlock while I was
raising it to my face. With Face ID, even with Raise to Wake, I
still have to wait until the phone is in front of me and then
swipe up. Face ID also fails in some circumstances where Touch ID
worked, such as lying sideways on a pillow in bed or wearing ski
googles. However, Face ID also has advantages. It works with
gloves on, with wet fingers, and with dry/cracked skin. It’s more
convenient when the phone is in a dock or car mount where it would
be hard to get my hand under it to put my thumb on the sensor.

That’s a great one-paragraph summary of the pros and cons of Face ID vs Touch ID. For me it’s a clear win for Face ID even though I run into the same cons as Tsai.

The display is amazing. I actually think it looks better than the
OLED screen on the iPhone XS. Text on OLED screens looks a bit
funny to me, especially when scrolling. There’s a weird color
effect that kind of reminds me of Microsoft’s ClearType.

I’ve been saying the same thing, including on a recent episode of my podcast talking to Joanna Stern, who just bought herself a XR for her own use. For using the iOS interface — Safari, Twitter, Mail, Messages — I really do think I prefer a great LCD to an OLED display. Where OLED’s advantages show most are when watching video — that’s when the deep blacks matter.
